Violet has 5 dimes and 15 quarters.

Step-by-step explanation:

let x denotes the number of dimes and y denotes the number of quarters.

Given : Violet has $4.25 worth of dimes and quarters .

Also, 1 dime = $0.1

1 quarter = $0.25

i.e.           (1)

She has 3 times as many quarters as dimes.

i.e                               (2)

Substitute the value of y in equation (1) , we get

Divide both sides by 0.85 , we get

Substitute the value of x in (2) , we get

Hence, Violet has 5 dimes and 15 quarters.
